You can use some of these figures to come up with what Tx power rating would be best for you. As factory lists it a max of 20dBm then a setting of 100mW could be used as 20dBm = 100mW 17dBm = 50mW and so on.

2.4GHz output power per TX chain

802.11b: Max. 20.5dBm @ All rates

802.11g: Max. 20.5dBm @ Low rates

Flashing instructions for the E3000

DON'T BRICK YOUR ROUTER! AFTER FLASHING WITH THE TRAILED BUILD, IF YOU THEN FLASH A BUILD THAT DOESN'T HAVE e2k-e3k in the NAME OF THE BUILD YOU ARE FLASHING YOU *WILL* BRICK YOUR e3000 ROUTER. ALSO reference this post regarding the newer NV60K.BINS FOR ALL E~ Series linksys http://www.dd-wrt.com/phpBB2/viewtopic.php?p=569485&highlight=#569485

Plug E3000 back in and wait about 5 minutes until it finishes booting.

Do a 30/30/30 reset on router.

Wait 3 minutes and log into web interface.

You may have to clear your browser cache before the web login will display.

You are done, but if you wish to flash another e2k-e3k build such as the 15692 e2k-e3k (must have e2k-e3k in the file name) follow the steps below. If you wish to (not recommended) flash a n60k build read the links about these new files above and below. You will need to flash a new post svn16773 e3000 file before flashing the n60k file. If you don't understand this, don't flash any builds past 16773 until you do.

Download the e2k-e3k/e3000 file you wish to flash.

Do another hard reset on your router

Login to the router at 192.168.1.1. Go to the administration/firmware upgrade page

Flash the file that you downloaded.

Wait AT LEAST 5 minutes until the WLAN light turn on, then unplug power on router and wait 30 seconds.

Plug power for the E3000 back in and wait about 5 minutes until it finishes booting.

Do a 30/30/30 reset on router.

Wait 3 minutes and log into web interface.

As of July 2010 you can only use the trailed builds with the e3000 name in it for initial flashing and nothing else, using other bin's without the e3000 name in it for initial flashing may result in a bricked unit! After you have dd-wrt installed to your unit, you can then use the e2k-e3k.bin's for upgrading to newer builds. Using builds without e2k-e3k in the filename after initial flashing WILL BRICK YOUR ROUTER!

Experimental Builds

There are some very new, very experimental builds available for the e3000. These have not been thoroughly tested and should not be used unless you have a problem with your current build that cannot be resolved with the builds you are using. Any build past 16773 requires a different build, rather than e2k-e3k, for subsequent flashing. The only build that is showing stability is the 18000 build (17990 and 18024 are effectively the same build) In order to use one of these experimental builds, you must ALREADY HAVE dd-wrt installed on your router using the instructions above. Following the steps in the peacock announcement note 1, http://www.dd-wrt.com/phpBB2/viewtopic.php?t=51486

The first Eko -nv60k build is 16773, the first official BrainSlayer -nv60k build is 16785.

If you have a pre 16773 build on the router then you can load either of BrainSlayers 16785 or 16994 builds
with file name ending in e2k-e3k, flashing any those files will be the step stone bringing you over to -nv60k type builds.

16995 is the last dd-wrt build with upgrade files of e2k-e3k type, all upgrading thereafter is done with -nv60k type files.

Alternative way of doing the transfer:

FIRST flash the trailed mini of 18000 for the E3000 first, (with E3000 in the name) then AFTERWORDS you can upgrade to a nv60k.bin for 18000. NOTE THAT YOU NEED TO USE THE 18000 build twice. FIRST the e3000 build and THEN the nv60 build. More info is here AND YOU SHOULD READ THIS BEFORE PROGRESSING: http://www.dd-wrt.com/phpBB2/viewtopic.php?p=569485

DD-WRT E3000 Build information

Always use the E~ series builds for upgrading. Anything else will brick your unit

The latest builds for this unit can be currently found in the FTP. Support was added in 14826 and on.

Also it has been asked about the builds with e2k-e3k name in them, these builds are for if you already have those units flashed with dd-wrt, you can simply use one of those builds to upgrade, but the initial flash should always be done with the trailed build (build with the unit only name in it) linked above. ALSO reference this post regarding the newer NV60K.BINS FOR ALL E~ Series linksys http://www.dd-wrt.com/phpBB2/viewtopic.php?p=569485&highlight=#569485

At step 5: "Wait 5 minutes until WAN light turns on". I waited for 5 minutes but the WAN light never turned on (I had no ethernet cable connected to the wan port). I didn't bother to wait for the WAN light to come up but I did wait the 5 minutes to continue with step 6 and further.

The steps above also apply for people running a converted E3000 with a stock linksys firmware. With these steps it is possible to flash your converted E3000 (running stock linksys firmware) with DD-WRT.

If you experience disconnects from the Internet/Network with this router feel free to try the following settings:

Printing

Printer Sharing gives a general description how to configure the router to connect a printer on the USB port. However it describes too much and things that are not needed or even not working for the E3000 router. Following procedure works with firmware DD-WRT v24-sp2 (12/24/10) mega, the latest version at the moment of writing.

This also indicates that a process p9100d is running looking at port /dev/lp0 which is a printer port

You don't have to install anything via ipkg or any other script. Everything is installed by default. So if you don't have the expertise to ssh to your router, don't despair, it is only to make sure that your router recognises your printer on the USB port.

To install the printer under Windows, use the following procedure:

Windows 7

Open Control Panel, Devices and Printers

Choose Add a printer

Add a local printer

Create a new port

Type of port: Standard TCP/IP Port

Hostname or IP address: 192.168.1.1

Make sure that the checkbox to query the printer and select a driver is not checked

Wait until the detection is done. It will say that the device is not found. Don't despair

Choose Custom and then click Settings

Make sure that Protocol Raw is selected and Port 9100 is entered. That will be proposed.
